SPECIFICATION forming part of Letters Patent No. 228,906, dated June 15, 1880, Application filed March 4,1880. (Model.) Patented in Belgium Fehrnary, 1880.

To all whom fit may concern:

Be it known that I, CARL KRUPP, of Vienna, in the Empire of Austria, have invented certain new and useful Improvements in Rotary Motors; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part ot' this specification.

This invention relates to an improvement in that kind of rotary motors commonly called disk-engines;7 and it consists in the combination of a revolving sphere, piston-wheel mounted on said sphere, and a revolving; steam-chamber surrounding the piston-wheel and revolving with the same, all constructed as. hereinafter set forth. The sphere is provided with suitable ports. A rotary valve is also provided, as also a pillow-block having ports for admitting the steam or other motive power.

This invention is illustrated in the accompanying drawings, in which Figure l is a vertical central section. Fig. 2 is a horizontal section, part of the machine being removed. Fig. 3 is a side view. Fig. 4 is a detached view, partly in section.

The remaining figures are details, referred to in their proper places.

Similar letters indicate correspon ding parts.

In the example shown in the drawings the letter A designates the frame of the machine, of metal or other suitable material. From this frame rise pillow-blocks a a', forming the bearings for a shaft, B. To this shaft is keyed a sphere, l), to whichsphere is attached the piston-wheel D E, or of which it forms a part.

The sphere bis provided with a flat circular face, which sits steam-tight against the rotary valve c c, but so as to rotate readily over the face of the same.

The piston-wheel consists of fan-wings D, standing inclined to each other, and connected by partitions E. This piston-wheel is surrounded by a steam-chamber, C, the sides h h of which form the frustums of cones, the apexes of the cones being at the center of the sphere b. The chamber C is preferably made in two parts, having rims a o. These rims n 0 have packing interposed between them, and are held together by screws or other means. Access can thus be readily obtained to the interior of the chamber. The sides ot' the chamber C must tit air or steam tight over the sphere b. The sides h of the steam-chamber are made convex at their inner surfaces, Fig. 4, while the fan-wings D are straight. By this means a space for the passage of steam is left between the fan-win gs D and sides h. The sphere b is provided with ports 3 4 for the passage of steam.

The rotary valve c rests on the shaft B, and it can be easily turned or reversed on said shaft by means of a cog-wheel or other suitable means, thus determining in what direction the driving parts are to revolve. The valve c is provided with portsl 2.

Aface view of the rotary valve c, showin gthe face toward the sphere b, is shown in Fig. 7. Fig. S shows the face of the sphere b, provided with ports occupying most of its face, so that when the sphereb revolves the steam or motive power has uninterrupted access to thc spaces between the fan-wings D and faces h. Fig. 6 shows the face of the rotary valve which lies toward the pillow-block whose face is shown in Fig. 5. The ports in the pillow-block a communicate with the ducts cl c, through which the steam or other motive power enters and ows out after finishing its work.

The steam or motive power entering through the duct d passes through the ports l l in the pillow-block, through the ports l 1 in the rotary valve c, and through the ports 3 3 in the sphere b, into the spaces between the fan-win gs D and sides h, over the tops of the fan-wings h, and out through the ports 4 4 and 2 2 into the eduction-pipe c.

As is seen on reference to the drawings, the edge or rim of the chamber C runs between rollers m min a ring, A', rising from the frame A. This ring holds the chamber C in an inclined position.

When the steam enters the spaces between the fan-wings D and the sides h it has a tendency to press the chamber C and piston-wheel apart, and thus vary the angle of inclinationof their axes. This is prevented, since the shaft B occupies a fixed position, and the fixed IOO ring A prevents the inclination of the chamber C from being altered. The consequence is, that a resultant motion is produced in the direction in which the chamber C and pistonwheel are free to movethat is, a revolution about their respective axes. When the rotary valve e is reversed the steam enters through the ports 4 4 in the sphere Z), and iiows out through the ports 3 3, since the relative position of the ports l and 2 and 3 and 4 is reversed and the revolution takes place in an oppositerllirection. The motion thus conveyed to the shaft B can be utilized for driving propellers, or any other purpose.

It' a pulley-wheel, F, is keyed to the shaft, belting can be applied to transmit the motion.

The advantage ot' this motor over the diskengine as constructed by Ericsson and Bishopp is, that the steam-chamber and piston-Wheel revolve together', in consequence ot' which the friction which takes place between these parts in the above-named machine is entirely 'done away with, and so much power is saved. In Bishopps engine, also, the piston-wheel wabbles, whichl circumstance is unfavorable for any powerful transmission ot' motion.

When the machine is to stop, the rotary valve c, Fig. G, is turned until the spaces marked 5 5, which before occupied the position coincident with the spaces 5 5on the pillow-block, Fig. 5, occupy the positions before taken by the ports l 2, when the flow ot' steam is cut oft'.

0f course, if the machine is to revolve only in one direction, the rotary valve c may be fixed in position, or the face of the sphere l) may sit directly against the pillow-block a. A suitable valve on the induction-pipe would cut oft' and stop the engine. In this case the rotary valve would be omitted.

In some cases it may be desirable to turn the machine about a vertical axis. For this purpose the lowest point of the ring A may be provided with a pivot, about which the machine can be turned. The passage for the steam or air maybe arranged in such pivot and connected with the ports in the pillow-block, if desired.

Heretofore ahollow shaft has been employed in rotary engines, so as to admit steam on the opposite sides of the cylinder, and then through curved pipes leading to a valve below, which c onstruction is not claimed by me.

What I claim as new, and desire to secure by Letters Patent, is-

l. The combination, in a disk-engine, of a revolving sphere, I), fitting steam-tight against a rotary valve, c, a piston-wheel.` D, having fan-wings inclined toward each other, and a revolving steam-chamber surrounding. said piston-wheel, all constructed and arranged substantially as described.

2. In a disk-engine, the combination of a sphere revolving against a rotary valve, c, a piston-wheel mounted on said sphere, having fan-win gs inclined toward each other, the partitions E, and the revolving steam-chamber, all constructed and arranged to operate substantially as described.

4. In a disk-engine, the combination of a sphere' provided with suitable ports and titting steam-tight against a rotary valve, which conveys steam to said ports, a revolving piston wheel mounted on said sphere, and a revolving steam-chamber surrounding said piston-wheel, all constructed and arranged substantially as described.

5. In a disk-engine, the combination of a sphere provided with suitable ports and tting against a rotary valve, having ports for conveying steam to said ports, mechanism, substantially as described, for shifting said valve, a revolving piston-wheel mounted on said sphere, and a revolving steam-chamber, C, all constructed and arranged substantially as described.

6. In a disk-engine, the combination ot' a sphere, b, provided with suitable ports and fitting against a rotary valve, c, with pillowblock provided with ports communicating with said valve, a piston-wheel mounted on said sphere, and a surrounding steam-chamber, O, all constructed and arranged substantially as described.

7. The combination, in a disk-engine, of a sphere, b, provided with ports 3 4 and partition D, and fitting against the rotary valve c, with suitable ports l 2, a pillow-block, a', having ports el c, the revolving piston-wheel mounted on said sphere, and steam-chamber C, revolving between rollers m m, all constructed and arranged substantially as described.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.
